In addition to all the other comments you can't now even successfully make a sandwich - my first customer ordered a ham sandwich, I gave him a ham sandwich and he rejected it for not being what he ordered.
Although the game is great I'm having problems with the sort of lag that would cause problems with the offline version turning the icons to say which key to press invisible. Otherwise an awsome game - I marked it down for the effects lag has on it though when I rated it - it would have been better to load the whole song rather than parts of it at regular intervals which seems to be causing the problem.
